Palit is not known for launching cutting-edge products ahead of the competition, as they can be described as the tortoise in a race against the hare. What Palit does do well is deliver a refined (read: not rushed) product to store shelves. The Palit Revolution 700 Deluxe is one such example, which offers the Radeon HD 4870 X2 with 2048 MB of GDDR5 video frame buffer and is cooled by a proprietary triple-slot thermal solution.

After a rather disappointing HD 3000 series, ATI took the world by surprise with the HD 4000 generation of graphics cards. Since the launch of the HD 4000 series back in June, ATI has reclaimed its presence in the market and has been steadily eating away at Nvida's marketshare. Benchmark Reviews has had the opportunity to review several cards from the HD 4800 series lineup and today we look at one of the newest additions to the family: the Radeon HD 4830. This particular model, the EAH4830, comes to us from Asus and sports a custom cooler design and factory overclocked memory. We'll put it through its paces and find out how it compares to its two closest siblings; the HD 4670 and the HD 4850.

ATI has learned that being the king of graphics means you must raise the bar for performance with each product release. Sapphire has taken this lesson, and engineered their own Radeon HD 4850 X2 as the latest evolution in graphics cards, and delivers a product nearly as grand as their Radeon HD 4870 X2. Benchmark Reviews has been fortunate to test the Sapphire Radeon HD 4850 X2 Dual-GPU video card 11139-00-40R against a collection of todays hottest video cards available.

Well the smoke has cleared, the dust settled and most of the rumors and hype have been laid to rest with regard to the first phase of NVIDIA's launch. For the last month or so the revised editions of the GTX 200 series are beginning to appear. Today at Benchmark Reviews it is our pleasure to review the Zotac GeForce GTX 260 AMP2! Edition. This graphics solution reputedly takes the GTX 260 to the next level of performance primarily due to NVIDIA's second generation architecture coupled the addition of 24 streaming processors, upping the total to 216. We fully intend to focus all our technology and energy to either prove or disprove that allegation.

MSI takes what ATI started, and clean up a few rough edges. There's no doubting the performance potential of any Radeon HD 4850, but taming the beast within has been another story. All too often the industry produces a product a little too hot to handle, and the RV770 GPU is one fine example. Plagued with high heat output, it takes the daring minds at MSI to calm fire with ice. Benchmark Reviews has already tested the high-performance cooling options dedicated to the Radeon HD 4870: Sapphire has their Toxic and Palit has their Sonic, but it seems that the big names have overlooked the warm-blooded 4850. In this article, Benchmark Reviews tests the MSI Radeon HD 4850 video card R4850-512M SKU- MS-V803-285.

It's a great time for those in the market for a new video card, in just a few short months we've seen the debuts of over half a dozen different boards. At the high-end, high-priced segment Benchmark Reviews has showcased such great offerings from NVIDIA as the GTX 280 and ATI/AMD's HD 4870x2, while at the other end of the spectrum the mainstream budget cards releases are almost too plentiful and mediocre to mention. This brings us to today's review of the mid-range Palit GeForce 9800 GT Super+ 1GB video card NE/9800TXT302 from NVIDIA. In the recent clamor of releases NVIDIA has quietly slipped in the 9800 GT, seemingly from nowhere and without much publicity.

Anyone who has heard of ATI video cards has probably heard of Sapphire Technology. Sapphire is the largest producer of AMD/ATI graphics products in the world, and do far more than rebrand a product with their own label. The Radeon HD 4000 series launched with tremendous success not long ago, and Sapphire has tweaked the design to produce their own high-performance Toxic Edition of the popular Radeon HD 4870 video card. In this article, Benchmark Reviews tests the 100243TXSR graphics card against the competition to find out if a factory-overclocked model is worth the money.
